STEADY-STATE POWER FLOW CALCULATION IN A HYBRID HVAC/VSC-HVDC GRID

摘要

Voltage source converter high voltage directcurrent (VSC-HVDC) transmission technology isincreasing its share in AC transmission due to importantadvantages such as independent P and Q control andlower harmonics. Nowadays, this technology is used toconnect far-away remote offshore wind-power plants tomainland networks. VSC-HVDC is the main actor indeveloping the future multi-terminal DC grids andsupergrids. This paper proposes a sequential algorithm tocalculate the steady state power flow in a specific hybridHVAC/VSC-HVDC grid which is a solution that is goingto be seen in the early stages of the planned supergid.
